Patent JP-H0772912-A (JP)
Title: Locus controller for articulated robot
Inventor: TOMITA KOJI
IPC: B25J9/10
Filed: 1993-09-03
Abstract: PURPOSE:To improve locus precision by multiplying deviation between a result in which the output of a rectangular coordinate system simulator part is inverse- transformed into a joint coordinate and an actual feedback value from a motor by a constant, and adding correcting it to the command value of the motor of each axis. CONSTITUTION:At the rectangular coordinate system servo simulator part 4 of a target locus correction part 3, the command values Xri, Yri,... in a rectangular coordinate system are inputted to a model control system, then, simulate computed results Xi, Yi,... can be obtained. At an inverse transformation part 5, and ideal state (alpha)=(thetaSd, thetaLd, thetaUd,...) for each axis can be obtained by applying the inverse transformation of the results into each joint coordinate. The deviation between both the ideal state alphar and the actual output alpha=(thetaS, thetaL, thetaU,...) of the motor is found by comparing by a subtraction part 6 to make the former coincide with the latter, and the deviation is multiplied by a prescribed constant by a constant part 7, and adds it with an addition part as the correction signal for each axis. In this way, it is possible to plot the the same locus in the rectangular coordinate system and a servo system provided with an independent driving axis corresponding to the rectangular coordinate system in one to one, which improves the locus precision.

Title: Heat treatment method for silicon wafer
Inventor: UMENO SHIGERU
IPC: H01L21/02
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To lower the density of oxygen deposition in the vicinity of wafer surface by a method wherein a silicon wafer, which is cooled under specific condition when crystal is grown by a Czochralski method, is heat-treated in an oxidizing atmosphere under specific conditions. SOLUTION: Silicon wafers, whose temperature of 450 to 550 deg.C is cooled down for two or more hours, and they are heat-treated at 1000 deg.C or higher for thirty seconds in an oxidizing atmosphere before conduction of a device process, or heat treatment is conducted at 1100 deg.C for ten, seconds in an oxidizing atmosphere. As a result, the oxygen deposition nuclei, generated in the cooling process of 450 to 550 deg.C, are contracted or vanished and the oxygen deposition deposit density in the vicinity of silicon wafer is lowered. The time of residence of crystal in the temperature range of 450 to 550 deg.C when crystal is grown becomes longer, and the oxygen deposition density in the vicinity of the surface after heat treatment is increased by the presence of oxygen deposit in high density. Therefore, the microscopic oxygen deposition nuclei are contracted or quenched.

Title: Floating type magnetic head supporting mechanism
Inventor: HORI SHIGEKI
IPC: G11B11/105
Filed: 1990-09-13
Abstract: PURPOSE:To obtain a stable magnetic head floating characteristic by using a rotating mechanism in the connection part between a seesaw type balancer or a floating slider and a supporting spring, to reduce the rotation moment of the floating slider. CONSTITUTION:A balance weight 8 is attached to a left balance arm 6 out of seesaw type balance arms freely rotatably attached to a position control arm 1 through a revolving shaft A5, and a floating slider 3 holding a bowl type magnetic head 4 is attached to a right balance arm 7. When the floating slider 3 is brought into contact with a magneto-optical disk 19 with the light load of the moment difference between right and left loads and the magneto- optical disk 19 is rotated in the direction of an arrow in such a state, the rotation moment difference between the right and the left and the floating force due to air are balanced to float the floating slider 3. Thus an influence upon the floating characteristic due to the surface shake of the magneto-optical disk is reduced, and contact between the floating slider and the magneto-optical disk due to a failure of floating or unstable floating is prevented.

Abstract: PURPOSE:To attain the use of an inexpensive frequency converter with making unnecessary spurious leakage adjustment by preparing two carriers in phase- locked with the burst signal in a first video signal with a first frequency converter, and respectively converting chroma signals with second and third frequency converters. CONSTITUTION:A phase locked loop circuit 24 generates continuous waves (frequencies: 6fSC1) in phase-locked with a burst signal (frequencies: fSC1). The continuous waves at the frequencies fSC1/2 and 3fSC1 obtained respectively from a 1/3 divider 25 and a 1/2 divider 26 are supplied to first and third frequency converters 31 and 32 as the carriers. A phase locked loop circuit 29 generates the continuous waves at the frequencies fSC2 in phase-locked with the burst signal of the second video signal, and supplies them to the frequency converter 31. Consequently, the frequency converter 33 prepares the continuous waves at the frequencies fSC2+2fSC1, and the frequency converter 30 obtains the chroma signals at the frequencies 2fSC1 by making them into the carriers. Further, the chroma signal at the frequencies 2fSC1 is converted into that at the frequencies fSC1 by the frequency converter 32.

Thereby, the latch circuit 18 is placed under a holding state. And, when transmission is completed, the latching operation of the latch circuit 18 is released, and the latch circuit 18 starts a differential switching operation based on the output of the oscillation circuit 19.

Title: Device for controlling operation
Inventor: MATSUO KATSUHARU
IPC: G05B19/02
Filed: 1987-09-29
Abstract: PURPOSE:To reduce a time to be needed for a specification change and a cost by providing a correcting resistance between an output port for temperature correction of a microcomputer and a voltage dividing circuit and changing the output condition of the output port in correspondence to an operation process to be executed. CONSTITUTION:For a microcomputer 1, in order to change the output condition of the output port for temperature correction in correspondence to the operation process to be executed, the voltage dividing ratio of a voltage dividing circuit 21 is caused to be a value in correspondence to the respective processes. An operation is controlled by the microcomputer 1 based on a voltage as a temperature detecting signal to be given from the voltage dividing circuit 21. Accordingly, only by exchanging correcting resistances 24-26 to the other resistance whose resistance value is different, the specification (the voltage dividing ratio of the voltage dividing circuit 21) of temperature control concerning the respective running processes can be independently changed. Thus, for the change of the specification of the temperature control, the correction of the software of the microcomputer 1 is eliminated.
